Why Are HIV Survival Rates Lower In The Deep South Than The Rest Of The US?

The Deep South region has become the epicentre of the US HIV epidemic. Despite having only 28 per cent of the total US population, nine states in the Deep South account for nearly 40 per cent of national HIV diagnoses. This region has the highest HIV diagnosis rates and the highest number of people living with HIV of any US region based on data for 2008-2011. And new research has found that the five-year survival rate for people diagnosed with HIV or AIDS is lower in the Deep South than in the rest of the country.

So why are we seeing higher death rates and lower survival rates among those living with HIV in the Deep South? The reasons are complicated, but poverty, social stigma, lack of health-care infrastructure and more rural geography likely all play a role.

Five year survival rates are poor

Recent research by the Centres for Disease Control and Prevention (CDC) and the Southern HIV/AIDS Strategy Initiative (SASI) at Duke University Law School in nine states of the Deep South — Alabama, Florida, Georgia, Louisiana, Mississippi and North and South Carolina, Tennessee and Texas — found that people diagnosed with HIV or AIDS in these states are dying at higher rates than those diagnosed in the rest of the country. This is the case even after controlling for regional differences in age, sex, race, and area population size.

CDC/SASI research found that 27 per cent of people diagnosed with AIDS in the Deep South region in 2003-2004 had died within five years of diagnosis. Although five-year survival varied among states in the Deep South, no state had a survival percentage at or above the US average, 77 per cent. In Louisiana, one-third of people diagnosed with AIDS and 19 per cent of those diagnosed with HIV had died within five years of diagnosis.

Researchers also compared the characteristics of those diagnosed with HIV/AIDS in the Deep South region to national averages and found higher percentages of young people (aged 13-24), blacks, females and transmission attributed to heterosexual contact among the region's individuals diagnosed with HIV. More than one-quarter of people diagnosed with HIV lived outside a large urban area, which is the highest percentage of any US region.

What makes the Deep South different from the rest of the US?

The Deep South has lower levels of income, education and insurance coverage than the rest of the US. Poverty is consistently associated with poorer health so it is not surprising that the Deep South is experiencing high death rates among those diagnosed with HIV. And none of the Deep South states have accepted federal dollars to expand their Medicaid programs under the Affordable Care Act, leaving thousands of people in the region without health insurance.

Geography also plays a role in the Southern HIV epidemic. Much of the Deep South HIV epidemic is concentrated outside of large urban areas. The CDC/SASI research found that living outside a large urban area at the time of HIV diagnosis significantly predicted greater death rates among people living with HIV in the region.

HIV-related stigma has been found to be higher outside the large urban areas and transportation is a significant barrier to medical care for HIV-positive individuals living outside urban areas since most HIV specialty care is located in urban areas. Without reliable transportation, people miss appointments and may lack access to supportive services such as case management, support groups and legal services.

Thanks to advances in HIV treatment, people who are diagnosed with HIV can have normal life expectancies. But that's only if they get linked to HIV medical care and remain on treatment, which is a challenge in a region where so many people live outside of urban areas, live in poverty or lack access to health care.

Stigma kills

HIV-related stigma has consistently been cited as a driver of the HIV epidemic — especially in the South. In the words of a Deep South focus group participant living with HIV, "HIV doesn't kill. Stigma kills."

HIV care providers in the Deep South region tell stories of patients who don't come to their medical appointments, who won't participate in support groups, who won't disclose their HIV status to their closest family members (and the list goes on) because of stigma and a deep fear of how they will be perceived if others discover their status. Stigma also prevents people from getting tested for HIV, which is a critical step in getting the right treatment and in preventing further transmission of the disease.

Southern laws and policies also contribute to stigma. Most Deep South states have abstinence-based sex education in public schools, which has not been shown to be effective in preventing sexually transmitted infections

Many Southern states also criminalise HIV-related sexual behaviours and prohibit syringe exchange programs, thus further marginalizing people at high risk for becoming HIV positive, such as sex workers and injection drug users. These laws also discourage HIV testing and make interventions that have proven effective, like syringe exchange, illegal.

Overcoming stigma and promoting prevention

The drivers of the Southern HIV epidemic are complicated and to a great extent mirror the causes of poor health outcomes overall in southern states. Creative programs, such as the expansion of telemedicine programs and the co-location of HIV care with other services, such as case management and mental health and substance abuse care, are important to overcome stigma and the lack of transportation and medical care in non-urban areas.

Funding to support anti-stigma interventions, including empowerment initiatives for those living with HIV and educational efforts for churches and community, is critical. Finally, increased prevention funding that is directed at urban and rural areas alike is crucial if we are to stem the new HIV diagnosis rates and lower the death rates in the Deep South.
